The Dancing Years 
The Morland Dynasty, Book 33

1919. As the euphoria of the Armistice fades, the nation counts the cost: millions dead or disabled, unemployment, strikes and shortages. As prices and taxes rise, it becomes harder to remember what the war was for.
Teddy tries to recreate balance but then a trip to France to see the place where Ned fell has unforeseen consequences; Polly, grieving for Erich Kuppel, persuades her father to send her to New York. Despite Prohibtion, the great city, pulsing with life, promises her a fresh start; Jessie and Bertie, detained in London by Bertie”s job, long to start their new life together; Jack becomes a pioneer of civil aviation, but when the company fails he”s faced with unemployment, with a growing family to support.
The generation that saw things no man should see must find relief from their own memories. A new world is struggling to be born out of the ashes; but as long as the music lasts, they will keep on dancing.
